in the faid spirit, and the Sprit {till remaining in a mianner Limpid, 
and void of the leaft Ray of Blew; if you drop into it a little Spirit 
of Sulphur, it is fomewhat forprizing to fee, that it immediately {trikes 
it intoa full Red, as ifit had been Blew before: and fo, if you drop 
Spirit of Sal Armoniac or other Alkaly upon it, it prefently {trikes it 
Green. Which further confirms what have been before {aid of the Can- 
Jes of Vegetable Colours. 
14. §. Itis alfo obfervable, That the Green Leaves of Barm, which 
give a Mufcadine Red, with fome Rays of Claret, to Water, gives a pure 
and perfec Green to Spirit of Wine: and is the only Plant of all 
that I have yet tryed, which doth the like. 
15. g. It is likewife to be noted, That both Yellow and Red Flowers 
give a ftronger and fuller Tiéure to Water, than to Spirit of Wines 
as in the Tindures of Comflip, Poppys, Clove-July-Flowers and Rofes,, 
made both in Water and spirit of Wine, and compared together, is 
eafily feen. So that for TinGures made with Flowers,whether for Me- 
dicines,or other purpofes, Water,with refpecé tothe Colour, is the better 
Menfirum. fay for Tinéfures made with Flowers; for there are 
fome other Parts, efpecially Gums, as Gamboja, Myrrh and Alocs; 
which give their Izméfures full and clear, only. to spirit of Wire. Some 
of which are ufed by Leather-Gilders, and others, for the wafhing over 
of Silver, fo as to give it the Colour of Gold. Thus far of the Colours 
of Plants asthey appear upon Infusion.

We foyle, Goosherry, Primrofe, Ferufalem Comflip, 
° “Bearfeare, Bearsfoot, Peony, Bistort, Lawrel, 
Goats-heard, droped upon Steel, make a Parple Tinéfure. But that of 
Vine Leaves {carce maketh any Ti#Gure at all. So that there is fome- 
thing elfe befides Sowerefs concurring to the Purple upon Steel. 
3. §. Saccharum Saturni droped on a Tingure of Red. Rofes, turn- 
eth it to a faint pale Green. 
4. §. Salt of Tartar droped upon the fame Tinfure, turneth it to
